STMICROELECTRONICS AEK-MOT-WINH92 Evaluation Board, L99H92QF, H-Bridge Gate Driver, Power Management - Motor Control

AEK-MOT-WINH92 is a Window lift DC board driver based on the L99H92 gate driver and an external MCU. evaluation board key objective is to drive a DC motor for car window lifters, ensuring high safety levels. This board perfectly fits in the automotive market trend, which goes towards the evolution of the window lift application, offering a new anti-pinch mechanism without leveraging on motor encoders but exploiting the board three different types of current sensing. The board can be configured to work with a single H-bridge for a bidirectional DC motor or two independent half-bridges for two unidirectional DC motors. Thanks to its compact size, the board can be connected to any microcontroller easily, exploiting separate and dedicated connectors for SPI communication, current sensing, and basic motor commands interface with fault detection capabilities. Another key feature is the adjustable gain for anti-pinch and for fulfilling any of the car window operative conditions.
